PAL increases not only the morbidity and mortality of patients, but also the length of hospital stay and costs. When a chest drain and suction fail to stop the PAL, surgical intervention is recommended according to the British Thoracic Society guidelines on pneumothorax treatment [1]. Pleurodesis is considered as an alternative treatment when surgical repair is impossible due to an underlying comorbidity. Diverse chemical and biological substances, including autologous blood [2], talc [3, 4], fibrin [5] and antibiotics [6], have demonstrated various efficiencies to treat PAL. Recently, an endobronchial valve (EBV) was successfully utilised to treat PAL [7–9]. Targeting the lung lobe or segment with an air leak is a prerequisite for stopping PAL using EBV. In the present study, we report a novel way of identifying the precise location of an air leak with a catheter-based device (Chartis system; Pulmonx Inc., Redwood City, CA, USA), which can measure airway pressure and … ER -
